Maybe they didn't understand me: in all previous FMs this didn't happen. I would put a start date between December 20th and 25th and, contracts that end, for example, on December 31st, 2023, when starting the save, the contract was the one entered in the editor, as well as the future departures of the players.
What happens in this FM is that, players with a contract until December 31, 2023, when starting the save on the custom date I mentioned above, the player's contract is automatically extended by 1 year and, those who were scheduled to leave at the end of the contract in 2023, are scheduled to leave in 2024.
The reason for this is that the calendar and contracts of players and clubs in South America are different from those in Europe. Our season starts in January.
